ledger.kak defines a region end that matches every character of
the buffer. This causes performance issues for large buffers.
Since the affected regions are only ever filled with a single color,
just use a regex highlighter instead of a region highlighter.
This improves performance when loading the file for the first time.

After opening a markdown file
```b
```
```c
int main() {}
```
markdown-load-languages will run an "evaluate-commands -itersel".
The first selection makes us run "require-module b", which fails
because that module can't be found. Since -itersel only ignores the
"no selection remaining" error we fail to run "require-module c". Fix
this by ignoring errors.
Dockerfiles of the form `Dockerfile.foo-bar` were not detected for syntax
highlighting.
Mainly meaning for this to capture _ and -, but I don't see why we wouldn't
capture any special character.
We often use the pattern «map global normal ": foo"». The space
after the colon is unnecessary since execution of the mapping won't
add to history anyway, since 217dd6a1d (Disable history when executing
maps, 2015-11-10).
With the parent commit, the space is no longer necessary for user
mappings, so there is no reason to continue the cargo-cult.
Remove the space from mappings to set a good example.
`x` is often criticized as hard to predict due to its slightly complex
behaviour of selecting next line if the current one is fully selected.
Change `x` to use the previous `<a-x>` behaviour, and change `<a-x>` to
trim to fully selected lines as `<a-X>` did.
Adapt existing indentation script to the new behaviour
The canonical way to disable all auto-insertion hooks is
set-option global disabled_hooks .*-insert
A recent change allowed to disable hooks that insert ) and }
independent of hooks that insert // (a step in the right
direction, we should do it for more filetypes).
Since the new hook ("go-insert-closing-delimiter") doesn't match
.*-insert, it broke the above snippet. Fix this by renaming it to
"go-closing-delimiter-insert".
This makes it a bit less obvious how to disable only comment insertion.
Not sure if there's interest in that, but make it easier by renaming
"go-insert" to "go-comment-insert".
In TOML's triple-quoted strings, it's allowed to place quotes just
next to the triple quotes.
foo = '''bar''''
^ part of the string contents
^^^ closing sequence
We greedily interpret the first three single quotes as closing
sequence. As a result the remaining single quote wrongly opens a new
string. Fix this by only treating triple quotes as closing if they
are not followed by another quote.
I don't think there is another possible interpretation of quadruple
quotes in TOML, so this should not affect other valid inputs.
